[Talk-ca] Fwd: [OSM-talk] Argh, Canvec imports

[Samuel Dyck]

Hi

I /think/ I'm responsible for the problems in Hudson Bay. The issue was 
I forgot to delete the intermittent coastline from Canvec and only 
discovered my error once the coastline was updated. I've fixed the 
problem, but I have no idea if I am responsible for that big blob of 
grey in the southern half (I didn't do any editing there, I have to wait 
until the next update to find out). I've seen coastline errors many 
times before, I remember there was a large one in Southern Ontario for a 
while, and Newfoundland had several until recently.

Here is the problem:
-Editors don't notice their mistakes until the coastline is updated, so 
they stick around in the data for a while
-When the mistakes are fixed it takes a few weeks for the corrections to 
show up on mapnik
-Coastlines are handled differently than the natural=water tag, which 
confuses people
-Mapnik doesn't render natural=water at high levels
-Mapnik ignores the water=intermittent tag

I'm not suggesting we use natural=water (that would be a terrible idea), 
there just needs to be a way for editors to check the rendering of their 
coastlines.
